# Newsletter

An occasional email about robots.txt, sitemaps, security.txt, llms.txt and the rest: what changed, how these files fail in public, and what true looks like.

## What you get

- Changes to how search engines, ad networks and AI crawlers read the files on your origin, explained plainly.
- New and revised standards, such as security.txt, llms.txt and ai.txt, and what they mean in practice.
- Field notes on how these files drift: migrations, CMS changes and staging rules that reach production.
- New Learn articles, and product changes once they have shipped.

## How often

Occasionally. An issue goes out when there is something worth your time, not to fill a schedule. Every issue has a one-click unsubscribe link.

## The kind of thing we write about

- Why a sitemap can list pages that robots.txt blocks, and how to spot it before search engines do.
- What the Expires field in security.txt is for, and what happens when it passes.
- How AI crawlers identify themselves, and what robots.txt can and cannot ask of them.
- What to check in the first hour after a site migration goes live.

## How your address is handled

- Double opt-in: nothing is sent until you confirm from the email we send you.
- One click to unsubscribe, from every issue, with no sign-in.
- Stored in our marketing systems, apart from the Flowpane product.
